Dear Ceph users,after upgrading from 19.2.0 to 19.2.1 (via cephadm) my cluster started showing some warnings never seen before:
29 OSD(s) experiencing slow operations in BlueStore
13 OSD(s) experiencing stalled read in db device of BlueFS
I searched for these messages but didn't find much. I also noticed that
when browsing the CephFS folders (using the kernel module for the
client) sometimes the client gets stuck for a long time before showing
the folder content; however I don't know if this can be related to the
above warnings.
I'd need help to understand what's going on and eventually how to troubleshoot it.
Thanks, Nicola
